SH OE ATTACHMENT FOR THRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 409,089, dated August 13, 1889.

7 Application filed May 9, 1889- Serial No. 310,177. (No model.)

To aZZ whom, it may concern.-

Be it known that I, LOREN M. WILSON, a citizen of the United States, of America, residing at Venice Centre, in the county of Cayuga and State of New York, have in vented certain new and useful Improvements in ShoeAttachments for Thrashing-lvlachinesyand I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to shoe attachments adapted to be used in connection with thrashing-machines,a part of one end thereof being placed under and in rear of the throat of a concave and the opposite end connected to a fan.

My invention consists in the construction and combination of devices, as will be more fully hereinafter described and claimed.

I have illustrated the invention in the accompanying drawings, wherein like letters of reference are used to designate similar parts in the several views, and in which- Figure 1 is a sectional elevation of the front end of a thrashing-machine, showing my improved shoe attachment in connection therewith. Fig. 2 is a perspective view of my improvement detached, and Fig. 3 is a transverse vertical section thereof through line :20 0c of Fig. 1.

A indicates the thrashing-machine, and B the shoe attachment. The latter consists of an elongated frame rounded at the ends and covered by metallic sheathings b. The one end I) of the frame depends below the opposite end to accommodate the inclination of the belt and the attachment of the deliveryscrew. WVithin frame B an endless belt or conveyer C is mounted upon suitably-propelled end shafts. This belt or conveyer fits snugly against the sides of the frame B, and has a series of buckets or troughs c secured thereon, the said buckets or troughs having back and end pieces and open at one side.

To one end of the frame B a rectangular frame d. is attached, having an outer closed end and an inner end with an opening therein aligning with an opening (1 in the said frame B. The frame d has a semicircular metallic lining or sheathing (1 depending below the under side of the said frame and extending into and partially through the openingd in frame B, to thereby guide the grain in through said opening into the belt 0. Centrally within the saidsemicircular lining or sheathing a worm-shaft D is mounted in suitable bearings, having a drive-pulley (l on the one end thereof.

To the under side of the lower depending part Z) of frame B another rectangular frame 6 is attached, the upper end of which adjacent to the frame B has a short semicircular metallic hood 6 secured thereto, and the under part provided with an elongated semicircular metallic trough 6 which extends from about the outer termination of the hood 6 to the farther side of the frame B, and thereby closes the bottom of frame 6 A shaft 6 with a drive-pulley c on the outer end thereof, is mounted in the frame c and extends centrally through the space inclosed by hood e and trough e to the farther side of frame B. On that part of the shaft e inclosed by the hood 6' and trough e a worm e is mounted, and the blades thereof arranged at such an angle as to feed outward toward the outer end of the frame 6 The said worm or screw a is situated directly under the delivering end of the belt C.

The screw or feeder D is inserted through the side of thrashing-machine A, close to the open part of the concave at the rear thereof. The grain, falling onto the screw D, is conveyed to the belt 0, and the buckets c thereofparrying it to the opposite end of frame B and dropping it onto the screw or worm conveyer E. The latter conveyer is suitably attached to a shoe or winnower, and the grain, falling upon said conveyer, is propelled or carried thereby into the fan.

A great amount of grain is wasted in the thrashing-machines now in use by being carried along with the straw. By my construction and arrangement I endeavor to avoid this waste, and arrange my device in connection with the concave, as set forth. By this means the grain is taken directly from the concave.

I can attach my improvement to either side of a thrashing-maehine, and thereby accommodate diflTerent constructions and arrangements.

\Vhen the improved attachment is used in connection with a thrashing-machine having an extended hopper, as shown in the drawings, the external discharge end of the attachment may be conveniently located beneath said hopper, so as to be out of the way.

Having thus described my invention, What I claim as new, and desire to secure by Lotters Patent, is

.1. The combination, with a thrashing-machine having a concave, of an attachment comprising an extended frame located external to the thrashing-machine and having an endless carrier arranged therein, a trough projecting laterally from said frame and extendingiuto the machine adjacent to the discharge of the concave and provided with an endless conveyor, and a discharge-trough lo- 2 5 cated laterally on the other end of the frame and extending externally to communicate with a winnower or fan, and an endless conveyer located in said discharge-trough, substantially as set forth.

2. The combination, with a thrashing-ma- 3o chine having a feed-hopper and a concave, of an attachment comprisingan extended frame located external to the thrashing-machine and having an endless carrier arranged therein, a trough projecting laterally from said frame and extending into the machine adjacent to the discharge of the concave and provided with an endless conveyer, and a dischargetrough located laterally on the other end'ot' the frame and extending externally beneath 40 the feed-hopper to communicate with a winnower or fan, and an endless conveyer located in said dischargetrough, substantially as set forth.

In testimony whereof I afiix mysignaturein presence of two witnesses.
